Marco Pierre White Jr has spoken out for the first time since checking into rehab.

The Big Brother star, who has hit the headlines over the summer for his outrageous and hedonistic lifestyle, confirmed on Twitter Saturday that he had gone through with his promise to get sober and was now on day two of his treatment - and already feeling better.

He wrote on Twitter Saturday: "I know it's only day 2 but I feel so much better.

"Feeling like s*** but in good way"

It came after Marco revealed in several tweets on Friday, that he had decided to enter rehab after splitting from his new girlfriend Holly.

In a series of one sentences, Marco wrote: “London you sl** I’m out. Not much left.

“Let’s just enjoy the f***ing hours. Out of London no need to go back.

“No one said it would be easy. Rehab. Single and getting sober.”

Marco, who has kept his followers in the loop on his wild nights out on Twitter and his Snapchat, has raised fears after boasting about suspicious white substances.

His behaviour has spiralled out of control, with Marco and a pal filming themselves downing a bottle of vodka, before he tattooed himself and then followed it up by piercing his face with a punching tool.

Beginning the night in Hoxton with a line of drinks and some pals, he wrote: "And the night strats we getting f***ing ahit faced [sic]."

He then documented the entire evening, before shamelessly telling his fans: "We getting f***ed up, cocaine on the way, everything we need."

Near-constant shocking rants

The caption read: "Cocaine on the way lets get on it do it for the team."

He appeared to skip some time, before re-appearing looking bleary-eyed with the caption: "I'm in trouble".

Several more clips followed as the bearded star rode in a taxi, but while he appeared to rant for some time, the sound was turned off.

Arriving at his destination, he then bent down in full view of his camera and filmed himself snorting lines of white powder.

He went on to rant: "What you got on me? F*** you. I'm rich, I'm famous, cars, money. Hate me, love me, I don't give a s***. I've got what you wish you had."

It appeared to go from bad to worse, as he revealed he had ended his relationship with girlfriend Holly, as he said: "I loved her with every ounce of me, but you know when someone shows their true colours, you know who they are as a person. At the end of the day, you can't be with someone who said they wished you died."

A representative from the Metropolitan Police told the Daily Star that it's unclear where the alleged drug use took place, so while arrests can be made due to content on social media, "specifics of times and places would be needed".

Marco later took to Twitter to annoucne he's "single" in a series of posts, writing: "I made that b***h famous," before adding: "On to the next."
